## Episodes
### Season 1 (2019–2020)

10 or 15 years after the Berke-Hulagu war, Ertuğrul Gazi goes to Konya and leaves his brother, Dündar Bey, in charge of his tribe. Dündar Bey is easily swain by others into doing their misdeeds, he falls into the trap of the devious Selçuk Sançak Bey, Alişar, and the merciless princess of Kulucahisar, Sofia, who seeks to kill all the Turks. Osman, Dündar's nephew, can see through Alişar and Sofia's plans and warns him about them, despite his refusal to listen. As they continue to build more tension against the Kayı, Geyhatu sends Komutan Balgay to cause more trouble and stop the Kayı, especially Osman, from rebelling against the Mongols. Dündar, who bows down to the Mongols becoming the Sançak Bey, can't see Alişar's anger over his position being given over to him and he believes him when Alişar blames Osman for his son's killing. Soon after, along with the threat from Kulucahisar, Dündar is shown the truth, that Alişar is beheaded by Osman, and Osman has married his love, Bala. Following this, after many difficulties, Balgay is presumably killed by Osman. While Kulucahisar is conquered by the Kayı, Sofia's death is happening in the process.

Aya Nikola is set to become the new Tekfur of İnegöl followed by Ertuğrul's return to the tribe. Meanwhile, Yavlak Arslan, the new Uç Bey, seeks to create his own state and sees Osman as an obstacle, later on they unite against the new threat from the new Han of the İlhanlı (transl. Ilkhanate), who allies with Nikola against the Turks of Anatolia. Bala also faces the arrival of Targun, Nikola's spy who allies with Osman to save her father, İnal Bey. Along with these problems, Osman is elected as the new Bey after his father's death, and he decides to marry a second wife according to his father's will. After Targun's death, Osman meets Malhun Hatun and initiates a major battle with the Byzantines, historically known as the Battle of Mount Armenia [tr] in which his nephew Bayhoca, gets martyred by Flatyos which results in Savci Bey and Lena killing Flatyos as well as Osman Bey trying to find the traitor in the Kayı, as his jealous uncle Dündar helps the Byzantines stir traps for him. Following the arrival of Ömer Bey, father of Malhun Hatun, Geyhatu sends Kara Şaman Togay to eliminate both Osman's Kayı and Ömer's Bayındır.
Meanwhile, Malhun is sent by her father to İnegöl to ally with Nikola against Togay. However she gets captured in the castle by Togay, who has already allied with Nikola. Osman also captures Nikola's ally Tekfur Aris, seeking to ally with him, Togay then delivers an ultimatum to surrender the Tekfur in exchange for Malhun. Osman decides to use the captured tekfur as bait to trap Nikola. However, Togay kills Aris on the way which gives Nikola an excuse to keep Malhun in captivity.
Nikola martyrs Zülfikar Derviş, Osman's spy in İnegöl, and also releases Malhun to gain the support of Ömer Bey, who seeks to sell him horses to infiltrate and conquer the İnegöl castle but the sale of horses angers Osman, who (not knowing their plan) orders them to be seized.
Meanwhile, Togay ambushes some of the Kayı on the way back from Boran Alp's unfinished wedding with Gonca Hatun, which results in the martyrdom of Abdurrahman Gazi. Osman later attacks the incoming Kalanoz, who is the younger brother of Kalanoz and was sent after Flatyos’ capture and death, after learning of his arrival indirectly from the Mongols, killing many Byzantine soldiers and Osman also invites all Turkmen tribes to join the attack except the Bayındırlı, angering Ömer Bey. Şeyh Edebali later calls Osman and Ömer Bey to Söğüt to resolve their differences, leading to Ömer Bey handing over Dündar's ring to Osman, exposing Dündar as a traitor. Although Simon, Petrus, and Hazal Hatun are exposed and captured first, Osman lures Dündar into a trap and then captures him. Dündar then is taken to the tribe and sentenced to death by Osman. Just as he is about to be strangled to death by the Alps, he requests to be shot by Osman instead, using the arrow that killed Bayhoca per Savcı's wish, and gets eventually executed, whilst Hazal is exiled to the Çobanoğlu tribe. Osman then initiates a major battle with the Byzantines, with the support of Malhun Hatun which is historically known as the Battle of Domanic [tr] in which Kalanoz martyrs Savci Bey and gets killed by Osman later on. In the battle, Osman had tricked Togay by promising taxes. But when Osman kicks out the messenger sent by Togay, who later kills him, the Mongol Governor, Wali Yargucu, complains to the vassal ruler of Selcuk, Sultan Mesud II, who invites Osman under the pretext of giving him gifts. After an argument, Osman agrees to pay taxes to the Sultan, who promises him future aid. Osman's reception by Mesud II angers Omer Bey, who decides to make a name for himself. Nikola uses Omer's anger and uses him to attack Togay. However, Nikola betrays Omer and Togay ambushes him. In the meantime, the Mongol forces raid Omer's tribe, which depresses him, causing him to go to Togay for revenge. Gets saved by Osman. To improve their relations, Osman marries Omer's daughter, Malhun Hatun. Later, when the Kayis are migrating to Domaniç, Togay attacks them and Bamsi Beyrek gets martyred. Osman later takes revenge by killing Togay in Soğut. In the meantime, Nikola begins preparations for a great war and fights a major battle against Osman, aided by Sultan Mesud II.

Bala Hatun gets better from her disease and comes to Yenisehir to meet Saadet Hatun but faints again after some time, when she gets better Osman asks her to stay in Sogut to protect the Sogut. The Crusaders launch an attack on Sogut where Bala, Alaeddin and Gonca Hatun fight off the intruders. The Crusaders draw back to instill fear. When Osman bey goes to the Mongol ambassador to seek revenge for his entering the tents disrespectfully, Yakup bey takes over Yenisehir because of the attack on Sogut after Mehmet bey blames Orhan, Alaeddin and Osman bey for the lack of security of Turk land. Yakup Bey sends Orhan and Mehmet to launch a surprise attack on the Crusaders. The spies in the palace (Veysel Alp) tell the enemies ahead and Mehmed and Orhan get captured. Alaeddin tries to get to the spies in the castle. When Osman comes back, he and Yakup Bey discuss what to do to get their sons back. Yakup Bey wants to give the castles back to the Crusaders but Osman objects and Yakup Bey orders him to stay back. Osman and Malhun Hatun secretly enter the Kestel with Holafira's help and save Mehmet and Orhan. Yakup Bey then doesn't give the castles to Tekfur. Back in Yenisehir, Bala Hatun and Alaeddin Bey stop Saddet Hatun from ruining Osman's secret plant to save the sons by putting Saadet, Gonca, and Cekrutyae in prison and Gonca feels like she is confused about Alaeddin since he is with or against her based on the circumstances. Osman and Malhun return with Mehmed, Orhan and Holofira.
Osman talks to the people in the Uch Bazar about how he is taking back his allegiance and how Kestel Kalesi belongs to Kayi. Yakup Bey is disturbed by this. Malhun Hatun is still persistent that Orhan not marry Holofira as Holofira is non-Muslim and will not be able to do anything for a rising Muslim state. Meanwhile Orhan proposes to Holofira. Alaeddin also confesses his love for Gonca Hatun in front of his siblings. Suddenly Karacelasun, a Mongol Komutan, seeks revenge after Osman killed his brother comes to Uch Bazar and destroy it, Bala Hatun and Malhun Hatun work with Alaeddin and Orhan to hold off the intruders. In the end, Osman Bey asks Mehmed where Yakup Bey is when his bazaar is attacked. This leads to even more distrust in Yakup Bey's ability to be sultan. Alaeddin tries to find a cure for the poison that seems to be inflicting all the wounded, including Gonca Hatun and Cerutaye Jr. He finds that the Mongols used an unknown fast acting poison. All are concerned with the current events and Osman is also slightly injured by a poisoned arrow while saving Yakup Bey and others from Mongols. Sometime later when everyone has recovered due to Alaeddin's cure, the Mongol Gorklu Han comes into action, wanting to marry the Byzantine princess Maria, but dies very early due to a cunning plan of Osman Bey along with the treacherous Christian commander Veysel. Later Holofira's evil aunts come into action when a group of scared Tekfurs summon her. Things become more difficult for Osman Bey when she calls Roma Celladi, who is a Selçuk Christian convert who came to Anatolia to crush the Turks. He martyrs Cavundur Bayinder, Uraz Bey, fatally wounding the former Mongol commander, Cerkutay Bey. Shamil Bey returns in action after taking Malhun Hatun back to her tribe, as she expected.
